lfb all whom it may concern:

Be itlrnown that l, SoLoMoN liAnrEN, a

citizen ol: `the United States, residing at Chicago, in the county Cool:y andtitate ot illinois, have invented a new and useful llmprotfcment in Sofa-Beds, of, which the toliowing is a specication;

lviiy inventionV relates particularly to comu bination .sofas and beds, in which a toldable ma'tti'ess-irame is normally housed within the main trame beneath the "seat ot the sofa and` equipped with a exible bed-bottoni, or wire mattress, the parts being so related as to atord room between the sections of the folded mattress for the bedding, a, the ma ttress-pad, or mattress proper, bed linen, and covers.

lliy primary object is to provide an improved construction ot the character indi cated which is durable, handy of operation, capable of being manufactured at a very moderate cost, and which affords'v a com` tortablc sofa ot pleasing appearance when in the sofa form, and which affords a thortl il ouglily comfortable bed when in the bed :torna lt may be preiminarily stated that in the preferred construction. of the invention which, is illustrated in the' accompanying drawings, there are employed a. main frame having' endstandards which constitute the arms of the sofa; a stationary baclr carried y said end-standards; a rearwardly swing- Seat pivotally mounted on the frame and ted tdassume a standing position ad mi; to the back; and a folded bed normally housed in said iframe beneath said scat, said' folding bed comprising front and bedr-sections nearing, a superposed re lationto each other in the folded condition oit the structure, and an intermediate' bedeection which. is pivoted on the trame land which is pivotally connected with the front and rear bed -sect1ons, said intermediate bedsection normally occupying a 'substantially vertical position beneath the .iront portion of the seat. v i

in the accompanying drawings-Figure It represents a sectional view of a combined sotaand bed constructed in accordance with my inventiomtlie structure being shown in bed form; Fig. 2, a similar sectionsliowlng the structure 1n soia form; Fig. 3, a broken 4 and 5, adapted, respectively,

` bers 8. Preferably,

perspective view showing the folded rela,

tion of the front, rear and intermediate,secM tions; and l3`ig..t, a broken plan sectional view'shovving the structure in bedform.

ln the construction illustrated, A represents a main trame; B1, a back'mounted thereon; C, a rearwardly -swinging seat pivotally connected with the mainV trame;

and D, a :folding bed normally housed in the main trame beneath the seat of the sofa.

The frame Amay be of any suitable construction and desi vn.' As shown, it coni'- prises end-standar s l; a rear connecting` member 2; and a lower front connectingA member 3. The end-standards 1 are equipped on their inner surfaces with stops, or rests, to support the rear and front bed-sections` in thefolded position., l

The'back Bimay be of any suitable conu struction. As shown, it comprises a( frame 6 and .an-upholstered padl 7, as indicated by dotted lines, the framef being rigidly connected withvthe rear portions of the endstandards of the main frame by angle-memthe back inclinesrearwardly and upwardly somewhat, as shown.

4 The seat C, as shown, comprises a frame 9 and an upholstered pad 10, which is indicated by dotted lines. The seat is connected near its rear edge with the main frame by pivots 11, and the seat is adapted to swing rearwardly and assumea standing position leaning against the baclr of the sofa, as shown in Fig. l'.

The folding bed D comprises a front section 12, a rear section 13, and an intermediete section 14.,` The front and rear sections are of substantially U-shape and have their arms connected, by pivots 15 .and 16, with the end members of the intermediate section 14. The end members of the intermediate section 11i areV connected with the endfstandards 1 of the main frame by pivotbolts 17., the connections being such as to prevent the end members of the intermediate section from being` drawn toward each other when the bed bottom is under tension. The members ot' the lbed-frame `-,are of angle-bar 'constructioiu and the horizontal `HangesV ot the end members ofthe intermediate section 14 are adapted to bear. upon the horizontal danges of the end members of the front and rear sections, as shown in Fig.l 1, in the extended position of the structure, whereby the front a'nd rear sections are supported with relation to the intermediate section by cantaliver action. A flexible bed-bottom, or wire mattress, 18, is applied to the folding bed-frame. Considering the structure in its folded condition, the pivotal connections 1T between the intermediate bed-section and the main frame are located nea'r the lower ends of the end members of said intermediate section, as appears from Fig. 2. The front bed-section 12 is equipped near its free edge with pivotally connected legs 19 which are provided at their upper ends with extensions connected by links 2O with the end members of the intermediate section ll. Pivotally connected with the inner portions of the end members of the front bedsection 12are links Q1, which. are connected by piv ots 22 with the upper ends of links 23, whose lower ends are connected by pivots 24 with the end-standards 1 of the -main frame at a distance beneath and somewhat inside the plane of the pivotal connections 17 'of the intermediate section ,of the bed. A pair of links 25 connect the rear portion of the rear bed-frame 'section 13 with the lower rear portions of the end-standards 1 of the. main frame.

'l`he`operation will bereadily understood from the foregoing description. The bed will usually be made up while the structure is in the unfolded condition shown in Fig. 1,

prior to converting the structure to sofa form. Afterthe mattress proper, bed-linen and covers have been applied, they are secured to the folding bed-frame so as to fold and unfold therewith. y

In converting to sofa form, the front bedsection is swung from the position shown in Fig. 1 to the position shown in Fig. 2, in which operation the legs 19 are folded with relation to the front bed-frame section, and

the intermediate bed-section let is caused to assume a vertical position. In this opera,- tion, also, the pivots 16 swing downwardly and the rear bed-section 13 is lowered so as to rest upon the stops 4. After the bed has been folded, the seat may be loweredl to the horizontal position, thereby housing the folded bed beneath the seat. Any suitable expedient (none shown) may be employed for concealing the folded bed at the front of the sofa. A front-piece 2G, connected by hinges-27 with the lower surface of the front portion of the seat-frame is shown.

In the operation of converting from sofa form to bed form, the seat is lifted to the standing position so as to rest against the back, and the bed is then unfolded by swinging` the section 12 from the position shown in Fig. 2 to the position shown in Fig. 1, in which operation the intermediate section 1t is swung on the pivots 17 and operates to only.

elevate the rear section 13. In the extended position of the bed, the links 23 assume an upright position' bearing against the pivotal connections 1T, and the links 21 serve as inner supports for the front. bed-section 12.

For clearness of illustration, the bedding is not shown in the drawings, but it is well understood in the art how the bedding may be applied and secured to the foldable mattress-f 1ame, or bed-frame.

The construction described is simple, durable, and may be manufactured at a'very moderate cost. The simplicity of structure ,and convenience of oper ition is contributed to materially by the employment of the rearwardly swinging seat adapted to assume a standing position adjacent to the back of the sofa. The mechanism by which the rear bed-section is elevated in the operation of unfolding the bed and the mechanism `bly means of which the front bed-section is supported in the extended position, are likewise of simple construction. While., in this construction, the rear portion of the rear mattress-fame section extends some distance in the rear of the pivotal portion of the seat when the bed is extended. it is observed that the bed is located a sufficient distance beneath the pivotal portion of the seat to prevent the rear portion of the seat from interfering with the occupancy of the rear section of the bed.

The foregoing detailed description has been given 'for clearness of understanding Therefore, no undue limitation should be understood therefrom, but the appended claims should be construed as broadly as permissible in View o ,f the prior art.

What I regard as new, and desire to secure by Letters Patent, is-

1. In a structure of the character set forth, the combination of a main frame comprising end-standards and aback fixedly secured between the rear portions of said end-standards, a seat pivotally secured at its rear portions to said end-standards and adapted to assume a standing position adjacent to said back, andan independent folding bed com-4 prising an intermediate bed-frame section having end-men'ibers normally occupying a substantially vertical position, pivotal connections between the end-members of said intermediate section and said frame at intermediate points of end-niembers, pivotal connections between the endsmembers of said intermediate section and said front and rear sections. a flexible bed-bottoni applied t0 said bed-frame sections. and means connected with the front "bed-frame section and serving to elevate the rear bed-frame section to the bed-forn'iing position in the operation of unfolding the front bed-franie section.
